Eye imaging in head worn computing

A method comprising:

• determining an operation mode based on a signal received by one or more sensors of the wearable head device, the wearable head device comprising a camera, a display, and a source of image light;
• receiving image light, via the source of image light, at a partially reflective surface of the wearable head device;
• presenting, via the partially reflective surface, the image light to an eye of a user of the wearable head device;
• in accordance with a determination that the operation mode comprises a first operation mode, capturing, via the camera at a first rate, eye-image light comprising a reflection of the presented light;
• in accordance with a determination that the operation mode corresponds to a second operation mode, capturing, via the camera at a second rate different from the first rate, eye-image light comprising a reflection of the presented light;
• and
• monitoring a health of the user based on the eye-image light.

A non-transitory computer-readable storage medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform a method comprising:

• determining an operation mode based on a signal received by one or more sensors of the wearable head device, the wearable head device comprising a camera, a display, and a source of image light;
• receiving image light, via the source of image light, at a partially reflective surface of the wearable head device;
• presenting, via the partially reflective surface, the image light to an eye of a user of the wearable head device;
• in accordance with a determination that the operation mode comprises a first operation mode, capturing, via the camera at a first rate, eye-image light comprising a reflection of the presented light;
• in accordance with a determination that the operation mode corresponds to a second operation mode, capturing, via the camera at a second rate different from the first rate, eye-image light comprising a reflection of the presented light;
• and
• monitoring a health of the user based on the eye-image light.
